Apply a reconciler to an input stream, with a given retry policy

Takes a store parameter for the core objects, which should usually be updated by a reflector().

The queue indicates which objects should be reconciled. For the core objects this will usually be the reflector() (piped through trigger_self). If your core objects own any subobjects then you can also make them trigger reconciliations by merging the reflector() with a watcher() or reflector() for the subobject.

This is the “hard-mode” version of Controller, which allows you some more customization (such as triggering from arbitrary Streams), at the cost of being a bit more verbose.
